Paste any YouTube URL and get auto-generated, timestamped chapters ready to copy into your video description.
How it works
Copy any public YouTube video URL or video ID and paste it above. Works with any video that has captions — manual or auto-generated.
Our AI analyzes the transcript to detect topic shifts, segment boundaries, and key moments — then assigns descriptive titles and accurate timestamps to each chapter.
Get a formatted list of chapters in your dashboard, ready to paste directly into your YouTube video description. YouTube automatically turns them into clickable chapter markers.
Features
Chapters are aligned to the actual content transitions in the video — not evenly spaced guesses.
Each chapter gets a clear, concise title that describes what happens in that segment — not just a generic label.
Output is formatted exactly as YouTube requires: timestamp followed by chapter title, one per line. Paste directly into your description.
Generate chapters for videos you've already published that don't have them yet — or for any competitor's video you want to study.
From 5-minute tutorials to 3-hour podcasts — the chapter generator adapts to the video's natural structure.
One-click copy from the dashboard. No reformatting needed.
Who is it for
Add chapters to improve viewer experience, reduce drop-off, and signal content quality to the YouTube algorithm.
Help students navigate long educational videos by breaking them into clearly labeled learning segments.
Make long-form podcast episodes searchable and skimmable by adding chapter markers to each topic change.
Generate chapters for any video to quickly map its structure before diving into a full analysis.
Use cases
If you have existing videos without chapters, paste each URL and generate chapters in bulk. Copy the formatted output into each video's description. YouTube immediately processes them as chapter markers — no re-upload required.
Videos with chapters tend to have higher average view duration because viewers can jump to the parts they care about instead of abandoning the video. Chapters also appear in Google search results as rich snippets, increasing click-through rate.
Generate chapters for a top-performing competitor video to instantly map its content structure — how long the intro is, when the core value is delivered, how the video ends. Use this to inform your own video planning.
For 60-90 minute podcast-style videos, chapters transform the experience from linear watching to topic-based navigation. Viewers return to specific segments; watch time and engagement improve.

FAQ
Copy the formatted chapter list from your dashboard and paste it into your YouTube video description. The first chapter must start at 0:00. YouTube automatically detects the timestamps and converts them into interactive chapter markers visible in the video player and on mobile.
Yes — in two ways. First, chapters appear as rich snippets in Google search results, showing specific moments from your video and increasing click-through rate. Second, viewers who can navigate to relevant sections are more likely to stay longer, which improves average view duration — a key signal in YouTube's ranking algorithm.
Yes. Any public YouTube video with available captions can have chapters generated. This is useful for studying competitor content structure, creating navigation for videos you're analyzing, or generating chapters for content you have the rights to but didn't originally create with chapters.
Accuracy depends on how clearly the video transitions between distinct topics. Videos with clear topic shifts, explicit transitions, or structured formats (like listicles or step-by-step tutorials) produce the most accurate chapters. Rambling or free-form content may have less precise segment detection.
YouTube requires at least 3 chapters and a minimum video length of around 10 minutes for chapters to appear in the player. For shorter videos, the chapters are still generated and can be added to your description — but they may not render as the visual chapter bar in the player.
The YouTube Video Chapters Generator from ytultra analyzes any public YouTube video's transcript and automatically identifies topic transitions, key moments, and segment boundaries — then generates a formatted chapter list with accurate timestamps and descriptive titles. Unlike manual chapter creation, which requires watching the full video and noting timestamps by hand, this tool produces a complete chapter list in seconds. The output is formatted exactly as YouTube requires: paste it directly into your video description and YouTube converts it into interactive chapter markers in the player. Use it to add chapters to existing published videos, improve viewer navigation for long-form content, boost average view duration and SEO performance, or quickly map the structure of competitor videos. Works with any public YouTube video in any language with available captions.
